What makes church, church?

I have been reflecting on what makes a church, church – and why we began a walking church. I think one of the reasons the church is feeling less and less like a church is due to a fine weather walker such a small group. At the beginning I thought the walking church would probably be a summer only church – and either this is the case, or we walk whatever. As a result, we have arranged to go for a longer circular walk around Levens Park.
